Find the book far to basic. The information that it provides can be found by simply googling the age of the baby,very disspointing. Was really expecting some more information regarding how to stimulate my baby's developmemt, what games to play etc. Having said that the title does not corresponds at all with what's in: the baby should sit up to 9 months and walk till year and a half- you can get this info anywhere without having to pay for it. We all know that our babies should sleep in their own beds. Some ideas please about how to achieve that!!!!! But it has nice photos and my baby loves looking at them.
